Embossing machine

In embossing machines for the production of printing forms for mressier machine technology or in the production of identification cards made of metal or plastic, devices are necessary with the aid of which the printing forms can be moved in two perpendicular seals. One direction is provided for the character step within a print or read line and the second direction, perpendicular to it, for the line advancement.

There are already a large number of execution formats for this transport device. Some of the oldest are on adjusted the paper transport devices for typewriters. To drive in the direction of the line, you can use one that is either manually or motorized Spring accumulator and generates the uniform drawing step

with the help of a rack or a ratchet wheel with a so-called switch lock, which, when actuated by a button, sets one tooth of the rack or of the ■ Releases the ratchet.

The line location is also similar to . on typewriters when the transport device is returned to the beginning of the line via a latch mechanism the line feed actuated. However, these devices, which have been tried and tested in themselves, can only be automated with a relatively large amount of effort. Automatic facilities, however, are for free-wheel-controlled - e.g. connected to electronic computers or readers Embossing machines are an indispensable requirement.

Particularly great technical effort has to be made if - "as is customary with identification cards, two fonts have to be used on an ID card: For example, the address of the ID card holder with a font approx. 2 mm high and a character division of e.g. 2.54 mm and a customer number in a stylized 4 mm high font - suitable for machine reading - and a character division of 3.63_ ram (= 1/7 inch). For this two separate step switching devices are necessary. The automation is further difficult.

The object of the invention is to design the transport device so that it is fully electric for all punctures controllable and therefore well suited for automation. This task is characterized by that in claim 1 Invention solved. Appropriate refinements are given in the "subclaims.

Here is the transport device for the two to each other perpendicular directions of movement. formed two mutually perpendicular spindle drives. Lend this the blank holder, preferably in a horizontal plane, the possibilities of movement that are required during embossing. the u spindle drives themselves do not yet define any reading distances, see above that their control with regard to drive and brake offers all possibilities leaves open. It is particularly favorable if the spindle drives each have one in the direction of rotation as the drive member reversible DC motor is assigned. In this way, the drive in the line direction is obtained in a particularly simple manner or the line return and also the drive for the line feed or the reset to the starting position.

For instant stopping the spindle when it is reached A disc brake, the brake disc of which is rotationally connected to the spindle, is expediently used in the embossing position. The brake lining is pressed magnetically onto the brake disc, which enables electrical control of the braking process is. A control disc rotating with the spindle is particularly suitable for this, from which the next ji Embossing position a brake signal is issued. By exchanging the control disc or arranging several, optionally switchable Control disks can be changed from one character division to another without difficulty. For that is It is favorable that a character division is not yet specified by the spindle drive itself.

In the case of automatic operation, precise confirmation of the division achieved by the transport device (character division and intermediate layer) is necessary in the Hegel. For this purpose, in addition to the control disks defining the character divisions, a control panel can also be provided on which the embossed positions p; & ken-n7.pi rh- _._ are coded, for example by changing between opaque and translucent fields. _._ BÖ9839 / Ö35T

are net. The control panel is controlled by a multiple light barrier scanned. One of the two parts is fixed; the 'other arranged movably with the circuit board holder./The The entire control system is therefore electric, quickly effective: and simply set up.

-j; -For the; mechanical structure, it is particularly favorable in the formation of the transport device from the two spindle drives lying perpendicular to one another if the plate holder is slidably slidable on a plate in a first shifting direction by a first spindle drive: or.driet, its Spindle rotatably mounted in the blank slide 1st, and! .Der; Blank slide itself in the machine housing in a second displacement direction perpendicular to the first by _: a second spindle drive is displaceably arranged, the spindle of which is rotatably mounted in the machine housing. Depending on the mechanical conditions, a further spindle or a guide rod can be parallel to each of the spindles.

Your rotation thus has a displacement of the blank slide "fö in the seal of the longitudinal extension of the spindle Π in the i'lgur to the left or right to the Pclge.

A circuit board holder 13 is displaceably mounted on the circuit board slide 10, and a C-winch nose 14, which extends towards the sheet metal slide and with which a spindle 15 is in engagement, is fixedly connected to the circuit board holder 13. The spindle 15 is rotatable in the blank slide 10, but not displaceably mounted in the longitudinal direction, the rotation of the spindle 15 therefore pulls the blank holder 13 back and forth over its displacement path 16 "depending on the direction of rotation of its motor VJ.

The circuit board holder 13 is intended for receiving and holding circuit boards ic which can be guided to it via a feed slot 19. Respectively received in the board holder 13 so Vo can board by the spindle drives for the board holder 13 itself or to the platinum carriage be brought to any desired Prägepositinn 10th

A motor 20 is provided as a drive for the spindle 11, which as well as the engine 1? one in its direction of rotation. is reversible DC motor. The spindle H is from Motor 20 is driven via an intermediate gear 21, which is, for example, a slip-free toothed belt drive. There the thread pitch of the spindle 11 in the Hegel does not match the desired character pitch is determined by the spindle 11, a control disk 23 is driven in a suitable transmission ratio via a further countershaft 22. For example, is the Spindle pitch 3 mm, but the required character pitch 2.54 mn

the required transmission ratio is 1: ü, U4öo. the Control disk 23 consists of opaque material. On hers. It has a "neckline" in scope, which runs into one Photocell. 24. As soon as the cutout is in the light barrier 24 arrives, gives this via an in iig. 2 schematically shown control a brake impulse, which is sent to a L'remsGagneteii 2! I is given.

■ .. "Mr den! '" All, since a second character division is necessary., Another control disk 2 / can be driven via a further back gear 26 with a suitable transmission ratio, which rotates in a light barrier 20. The transmission ratio of the back gear 2b is selected, for example, so that b now a character pitch of Ί / 7 inches or 3.62c] mm is achieved. The light barrier 2LJ also generates via the in i'ig. Control indicated in FIG. 2 when the section of the control disk 27 enters a braking pulse which can be given to the braking magnet 25. Depending on which of the two control disks 23, 27 is active or which of the two light barriers 24, 28 is connected to the brake magnet 25 via the control circuit, the result is a different division of characters.

The spindle 11 of the spindle drive for the longitudinal movement, in the direction of the line carries a thin, in the axial direction elastic brake disc 29, which in connection with the brake magnet 25 a fast acting disc brake forms. The brake disc 29 is arranged so that they constantly under slight pressure on the fixed brake pad 30 slides. The movable armature 31 with the second brake lining

Zy pressed. The resulting slight continuous braking of the Spindle Π can practically be neglected. To this However, it is also ensured that when the brenisirapulse arrives from one of the light barriers 24, 28 the braking force on the 4ÜÜ to ^ OÜ-iachen i / ert increases, so that the Spb.de 1 Ti is stopped in a very short time.

To ensure that the sinker slide runs smoothly 10 to ensure on the spindle TI is the plate slide 10 additionally guided on a guide rod 35 arranged in the machine housing 12. This can also be used as a Spindle be designed, which is then driven in the same way and at the same speed as the spindle 11.

With the sinker carriage 10 is also another multi-part control panel 36 of the embodiment shown in the figure connected, in the manner shown by a multiple light barrier 37 is scanned. Each character position or embossing position, for example, can be used in this way corresponding control signal can be assigned. In the event that two different character pitches are used Of course, two such control panels and two multiple light barriers must be provided, in the example shown the control panel 36 on the board slide 10, the multiple light barrier 37 attached to the machine housing 12. However, it is just as well possible to firmly connect the control panel to the machine housing 12 and one of them to the board slide 10 scan moving multiple light barrier 37 allow.

The spindle Vj with its motor 17 is mounted in the sinker slide 10 in the manner explained above, and the motor 17 engages the spindle Vj via an intermediate gear. With that, however, on this
